What Is The Solubility Of Silver Sulfide?

Silver sulfide (Ag2S) is sparingly soluble in water, meaning that it only dissolves to a very small extent. The solubility of silver sulfide depends on the conditions under which it is dissolved, including temperature, pH, and the presence of other ions.

At room temperature, the solubility product constant (Ksp) for silver sulfide is approximately 6.3 x 10^-51, which means that only a very small fraction of Ag2S will dissolve in water to form Ag+ and S2- ions. This makes silver sulfide essentially insoluble in water.

However, the solubility of silver sulfide can be increased by altering the conditions under which it is dissolved. For example, increasing the temperature or decreasing the pH can both increase the solubility of silver sulfide. In addition, the presence of other ions in the solution can also affect the solubility of silver sulfide.

Overall, the solubility of silver sulfide is very low in pure water at room temperature, but it can be increased by changing the conditions of the solution.
